## Abstract The ^13^C spectra and ^13^C longitudinal relaxation times (__T__~1~) were measured to investigate the segmental motion of the neat ionic liquid 1‐butyl‐3‐methylimidazolium bromide ([bmim]Br) in the super cooled state. The ^13^C signals of the imidazole ring significantly broadened at 28
